摘要

A new cobalt(II) complex,[Co~(II)(phen){3,5-(NO_2)_2sal~(2-)}]_n(1) (3,5-(NO_2)_2sal~(2-) = 3,5-dinitrosalicylate anion,phen = 1,10-phenanthroline),the first cobalt(II) complex with 1,10-phenanthroline and 3,5-dinitrosalicylate acid ligands,has been prepared by hydrothermal synthesis and characterized by single crystal X-ray analysis,IR,XPS spectra,TG-DTA analysis and elemental analysis.This compound displays a linear one-dimensional (1D) chain though cobalt atoms and bridging carboxylate groups of 3,5-dinitrosalicylic acid ligands with Co...Co distance of 4.085 A.Magnetic susceptibility measurements show weak antiferromagnetic interactions in the complexes.
